JAMES a coNTEnIo, or SAN FRANCISCO, CALIFORNIA.

CORNER-BRACKET.

To all whom it may concern:

Be it known that I, JAMES A. CoNTnRIo, a citizen of the United States,residing at San Francisco, in the county of San Francisco, State ofCalifornia, have invented certain new and useful Improvements in ingsurfaces to thus avoid the necessity of providing attaching membersdriven into the supporting surfaces, whereby the bracket may be appliedor removed in a most ready manner, and without marring the supportingsurfaces.

It is in general the object of the present invention to simplify andotherwise improve the structure and to increase the supportingeiliciency and the ease of application of dev ces of this character, andit is more particularly an object to provide a bracket of the presentnature, which when not in use may be folded to occupy a minimum amountof space.

A further object resides in the provision of a bracket of the presentnature including foldable body bars and a supporting shelf foldable uponfolding movement of said :bars, whereby said shelf and bars may beretained in difiere'nt angles in various manipulations of the device.

With the above and other objects and advantages in view, the inventionresides more particularly in thenovel combination, formation andarrangement of parts hereinafter described and particularly pointed outin the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view with the supporting surface broken awayand showmg the device as when mounted in the corher of abutting walls.

Fig. 2 is a top plan view thereof. V Fig. 3 1s a transverse sectionalview on the line 3-3 of Fig. 2.

Fig. 4 is a longitudinal sectional view Specification of Letters Patent.

Application filed August 9, 1918. Serial No. 249,184.

through a part -of one of the horizontal frame bars of thebracket.

Fig. 5 is a sectional view taken vertically through the device andintersecting the angle of its side portions.

Fig. 6 is a view showing a modification of the frictional supportengaging means of the bracket.-

. Referring now more particularly to the drawings, the body frame of thebracket comprises a pair of bars ,5 and 6, preferably formed of aluminumto provide sufficient strength with a maximum lightness, and each barhas one end laterally directed at 7 for securement thereto of one leafof a hinge 8, whereby said bars may be folded to lieagainst each other,or may be swung to form any desired angle, the laterally turned ends ofthe bars being extended inwardly of the angle formed thereby, and thehinge leaves being secured to the outer faces of said laterally turnedend portions. For frictionally securing the bracket bars to the wallsurfaces at the corner of a room or to anyother desired angular support,rubber suction pads or cups 9 are distributed along the outer faces ofthe bars 5 and 6, each cup being secured to its bar by a screw 10threaded through'the bar and threaded into a nut'll embedded in a boss12 of the rubber' cup. For urging the bars against the supportingsurfaces, a spreader is employed. This preferably consists of anextensible and foldable brace rod detachably secured to Y theintermediate portions of the bars 5 and 6 and this rod comprises outersections 13 having their ends laterally bent to engage in socket plates14 secured on the inner faces of the bars 5 and 6. Pivotally secured tothe ends of the outer sections 13 are threaded sections 15 having theirinner ends engaged in a turn buckle sleeve 16, the pivotal connectionsbetween the threaded sections 15 and the outer sections beingslidable sothat the ends of 'the said sections 15 may seat in socket recesses 17 ofthe outer sections to prevent relative pivotal movement of the sectionswhen expanding pressure is set up within the spreader by rotating theturn buckle sleeve.-

To assist in supporting the bars 5 and" 6, a pair of supplemental andpendant bars 18 are r'ovided, each having one end eccentrica 1y pivotedto the lower edge tion of a main bar whereby it may old closelythereagainst and having distributed along its outer face rubber cups 19similar to the cups 9. For urging these bars frictionally againstangular supporting faces for the bracket, a spreader is provided similarto that of the main bracket bars, and comprising outer sections 21having laterally turned ends engageable in socket plates 22 obliquelysecured on the inner faces of the bars 19, these outer sectionsbeingpivotally connected with threaded sections 23 engaged in a turn bucklesleeve section 24:.

The entire bracket structure thus described may be folded when not inuse to occupy a minimum amount of space and may be readily securedfrictionally to a pair of angular supporting faces, the cups formingvacuums in connection with smooth supporting surfaces to firmly hold thebracket bars against displacement.

Particularly for use on rough surfaces, the rubber cups may beeliminated and the modified structure shown in Fig. 6 utilized, whereinthe outer faces of the bracket bars have secured thereto rubber frictionpads or plates 25 having transverse teeth facing away from the angle ofthe bracket.

To provide a shelf surface permanently associated with the bracket barsand foldable therewith upon folding of said bars, a series of taperedplates or leaves 26 are provided, having their side edges hingedlyconnected to form a fan like structure, the outer side edges of theouter leaves being hingedly secured to the upper edge portions of thebracket bars 5 and 6. Thus, when the bars 5 and 6 are disposed insubstantially right angular position, the leaves 26 present a flat shelfsurface.

It will, however, be appreciated that the bracket bars 5 and 6 may beutilized for supporting a separable shelf, and that various otherchanges and modifications may be resorted to without departing in anymanner from the spirit of the invention.

l/Vhat is claimed is:

1. A bracket comprising a pair of hingedly connected bars, frictionmembers on the outer faces of said bars, a spreader having its endspivotally connected with the bars, bars depending from the first-namedbars, and a second spreader having its ends ]pivotally connected with.the last-named ars.

2. A bracket support comprising a pair of hingedly connected bars,friction members on the outer faces of said bars, an extensible rodhaving its ends pivotally connected with the bars, bars pivotallyconnected with the first named bars, friction members on the outer facesof said second named bars and a rod having its end ivotally connectedwit-h the second named bars.

3. In a corner bracket, the combination with a pair of bars connected atone end at an angle to each other and having upright sockets on theirinner faces and friction pads on their outer faces, and barsrespectively depending from the first bars and having oblique sockets ontheir inner faces: of a spreader having bent ends removably engagingsaid upright sockets, and a second spreader having bent ends removablyengaging the other sockets.

4. In a corner bracket, the combination with a pair of bars connected atoneend at anangle to each other and having upright sockets on theirinner faces, and friction pads on their outer faces; of a spreaderhavingbent ends removably engaging said upright sockets, a pivot withinthe len th of the spreader, and means for nullifying the pivotal actionthereof when the spreader is forcibly distended.

5. In a folding corner bracket, the combi nation with a pair of barshinged together at one end, friction pads on their outer .together edgeto edge and with the outer edges of the outer leaves connected to thefirst-nal ned bars.

6. In a folding corner bracket, the combination with a pair of barshinged together at one end, suction cups on their outer faces. aspreader between the bars having a pivot within its length, barsdepending from the first bars and a spreader between the depending barsalso having a pivot within its length; of a fan-like folding shelfcomposed of tapering leaves hinged together edge to edge and with theouter edges of the outer leaves hinged to the first-named bars.

In testimony whereof I affix my signature, in the presence of twowitnesses.
